Therefore, you can imagine what it looks like: as shown in the figure below, this thing is called industrial silicon.
Industrial silicon may look ugly, but it is very capable. Starting from industrial silicon, there are three branches:
First: aluminum alloy,
Second: polysilicon,
Third: organic silicon,
